Focus: TIM250 will focus on getting students familiar with core principles in Stochastic Optimization, grounding these principles in both (1) examples taken primarily form online advertising (a $65 Billion industry) and in (2) example projects and code in R and Matlab. Each class will be composed of theory, practice and problems, thereby informing and inspiring students on how to apply theory to practice.

The course is being taught a technical leader in the field of online advertising with over 25 years of research and development experience at world renowned research labs such as Xerox, AT&T and Clairvoyance. In addition, the instructor has broader experiences in web search, online advertising, information retrieval, statistical data mining and machine learning.

You will learn some of the following skills:

  • Analyze intelligent support systems for marketing decisions as well as develop mathematical models for optimizing sales, marketing, and pricing decisions in high tech
  • Learn the core subjects of optimization theory: gradient descent; classical programming; nonlinear programming; and linear programming. See how they are used every day in machine learning and in online advertising.
  • Learn basics of dynamic programming and Markov decision processes(MDP), including value and policy iteration  for finite and infinite horizon situations. Look at applications setting policies for online adverting to optimize various business objectives
  • Students will get to work on a real-world problem (with real data) in the area of Online advertising, that of predicting real-time bids on behalf of advertisers. Dr. Shanahan is a judge for this competition, which is organized by IPinYou. The competition has a grand prize of $160,000 (and lots of prestige).
  • Study online learning, whose core focus is learning in an explore-exploit mode, in a one example at a time; this is key to understanding, analyzing, and stimulating research in the field of learning in a non-stationary environment such as serving digital ads online; study multi-arm bandit approach to ad serving.
  • Stochastic Recommenders: review classical approaches to collaborative filtering while also looking at recent developments in the field of stochastic recommenders with applications to ecommerce and online advertising
  • Game Theory: auction mechanism design. Time permitting, we will cover game theory and study its application to online advertising auctions. This is an area that has and continues to revolutionize the economic models of online advertising

The course emphasis will be tuned to the class composition and interest.

Prerequisites: Students are expected to be mathematically mature, and to have had prior exposure to undergraduate linear algebra at the level of  MATH21 or  AMS10  and probability/statistics at the level of AMS 131 or MPE 107.

Instructor biography:

Dr. James G. Shanahan, Independent Consultant, San Francisco

Jimi has spent the last 25 years developing and researching cutting-edge information management systems that harness machine learning, information retrieval, and linguistics. During the summer of 2007, he started a boutique consultancy (Church and Duncan Group Inc., in San Francisco) whose major goal is to help companies leverage their vast repositories of data using statistics, machine learning, optimisation theory and data mining for big data applications (billions of examples) in areas such as web search, local and mobile search, and digital advertising and marketing. Church and Duncan Group’s clients include Adobe, AT&T, Akamai, W3i, Digg.com, eBay, SearchMe.com, Ancestry.com, TapJoy, and SkyGrid.com. Along with architecting and developing large scale distributed statistical optimization systems for his clients, Jimi also leads and hires engineers and scientists, and provides business insights and strategic guidance to sales, analytics and business development groups within these organizations. In addition, Jimi has been affiliated with the University of California at Santa Cruz since 2009 where he teaches a sequence of graduate courses on big data analytics, machine learning, and stochastic optimization (TIM 206, ISM 209, ISM 250 and ISM251). He advises several high-tech startups (e.g., Quixey.com, W3i, InferSystems) and is executive VP of science and technology at Irish Innovation Center (IIC). He has served as a fact and expert witness.

Prior to founding Church and Duncan Group Inc., Jimi was Chief Scientist and executive team member at Turn Inc. (an online ad network that has recently morphed to a demand side platform).  Prior to joining Turn, Jimi was Principal Research Scientist at Clairvoyance Corporation where he led the “Knowledge Discovery from Text” Group. In the late 1990s he was a Research Scientist at Xerox Research Center Europe (XRCE) where he co-founded Document Souls, an anticipatory information system, where documents were given personalities of information services that foraged the web to stay informed and informative. In the early 90s, he worked on the AI Team within the Mitsubishi Group in Tokyo.

He has published six books, over 50 research publications, and 15 patents  in the areas of machine learning and information processing. Jimi chaired CIKM 2008 (Napa Valley), co-chaired International Conference in Weblog and Social Media (ICWSM) 2011 in Barcelona, and was PC co-chair of ICWSM 2012 (Dublin). He co-chaired the ISSDM Workshop on Knowledge Management: Analytics and Big Data at UC Santa Cruz.  He has organized several workshops in digital advertising as part of SIGIR, NIPS and SIGKDD. He is regularly invited to give talks at international conferences and universities around the world. Jimi received his Ph.D. in engineering mathematics from the University of Bristol, U. K. and holds a Bachelor of Science degree from the University of Limerick, Ireland. He is a Marie Curie fellow and member of IEEE and ACM. In 2011 he was selected as a member of the Silicon Valley 50 (Top 50 Irish Americans in Technology).
